linux-user: Add strace support for printing arguments of chown()/lchown()

This patch implements strace argument printing functionality for syscalls:

    *chown, lchown - change ownership of a file

        int chown(const char *pathname, uid_t owner, gid_t group)
        int lchown(const char *pathname, uid_t owner, gid_t group)
        man page: https://www.man7.org/linux/man-pages/man2/lchown.2.html

Implementation notes:

    Both syscalls use strings as arguments and thus a separate
    printing function was stated in "strace.list" for them.
    Both syscalls share the same number and types of arguments
    and thus share a same definition in file "syscall.c".
    This defintion uses existing functions "print_string()" to
    print the string argument and "print_raw_param()" to print
    other two arguments that are of basic types.
